Abstract: PURPOSE:To connect many transmitters by varying a voltage, based on a voltage variation generated across a resistance whose resistance value is small. CONSTITUTION:The power source is provided with a constant-voltage diode 7 for varying a supply voltage at the time when a voltage variation detecting circuit 6 detects a line current variation, a relay contact 8 used as a switching element whose state of turn-on/turn-off is determined in accordance with a current value of a variation detecting time point.
